Re-flying each wall loss with that dodge and its speed-matching both taken away saved about 96 in 100; speed-matching alone saves about half. The saved craft passed about 10 m closer to other-level craft but made no contact in the next 10 seconds. A counterfactual on one craft at a time; nothing is switched on.</description><pubDate>Mon, 12 Oct 2026 12:00:00 GMT</pubDate></item><item><title>Eleven held haulers flown six ways: the release speed decides.</title><link>https://wooh.lv/equilibrium/flight-log/eleven-held-haulers-flown-six-ways/</link><guid>https://wooh.lv/equilibrium/flight-log/eleven-held-haulers-flown-six-ways/</guid><description>Eleven held heavy haulers, chosen by fixed rules from the previous cycle (so not a rate), were each flown six ways under two autopilot plannings. Changing only the speed at which the simulator lets them go, from rest to cruise, changed every ending, and the hauler then ended like a normal arrival in 21 of 22 cases. Letting it go a third of a second later changed one ending; the pad clearance check and bookkeeping changed none. Nothing is switched on.</description><pubDate>Mon, 12 Oct 2026 12:00:00 GMT</pubDate></item><item><title>Move the lanes, move the danger.</title><link>https://wooh.lv/equilibrium/flight-log/move-the-lanes-move-the-danger/</link><guid>https://wooh.lv/equilibrium/flight-log/move-the-lanes-move-the-danger/</guid><description>At one simulated street crossing, the same four one-way lanes were re-stacked over the same four heights. The danger did not stay with one lane: on each of three stackings one lane took almost all the in-band wall losses, and it was a different lane each time. A fourth stacking lost almost no craft at all. Why is not yet tested: this is a clue for one crossing in calm air, not a recommendation, and nothing is switched on.</description><pubDate>Sun, 11 Oct 2026 12:00:00 GMT</pubDate></item><item><title>A quicker hauler survives the gusts too, and it is mostly the autopilot’s planning.</title><link>https://wooh.lv/equilibrium/flight-log/a-quicker-hauler-survives-the-gusts-too/</link><guid>https://wooh.lv/equilibrium/flight-log/a-quicker-hauler-survives-the-gusts-too/</guid><description>With the steady cross wind, gusts and turbulence together, a hauler with a quicker assumed response made about 5 bad landings per 100 at 1.5 m/s where the assumed slow hauler made 47. Under the steady wind alone, quicker autopilot planning on the slow machine was already enough; with gusts, the planning did about 60 per cent of the work. Both response figures are assumptions, not sourced for a real craft.</description><pubDate>Sun, 11 Oct 2026 12:00:00 GMT</pubDate></item><item><title>Switching off speed-matching between levels: the saving and its price.</title><link>https://wooh.lv/equilibrium/flight-log/switching-off-speed-matching-between-levels/</link><guid>https://wooh.lv/equilibrium/flight-log/switching-off-speed-matching-between-levels/</guid><description>Turning off one controller term, the one that makes a craft match the velocity of craft on the neighbouring height level, kept saving craft wherever the term could act: with exact height knowledge, under a 4 m own-height error, on wider lane spacing and in the demonstration fleet. The price is band-keeping: craft spent somewhat more of their flying time outside their assigned height band. Nothing is switched on; whether to change the default is an open decision.</description><pubDate>Sun, 11 Oct 2026 12:00:00 GMT</pubDate></item><item><title>The heavy drone’s steady-wind landing loss is the slow body we assumed for it.</title><link>https://wooh.lv/equilibrium/flight-log/the-steady-wind-loss-is-the-slow-body-we-assumed/</link><guid>https://wooh.lv/equilibrium/flight-log/the-steady-wind-loss-is-the-slow-body-we-assumed/</guid><description>Under a steady side wind alone, bad landings rise as a ramp from 1.35 m/s to about one in four at 1.5 m/s. Giving the same hauler a quicker response, or a gentler final slope, left none in 1,720 landings at 1.5 m/s. In this model the loss belongs to an assumed response time that has not been sourced for a real craft.</description><pubDate>Sun, 11 Oct 2026 12:00:00 GMT</pubDate></item><item><title>Which part of the wind spoils the landing.</title><link>https://wooh.lv/equilibrium/flight-log/which-part-of-the-wind-spoils-the-landing/</link><guid>https://wooh.lv/equilibrium/flight-log/which-part-of-the-wind-spoils-the-landing/</guid><description>It depends on the wind. At 1.5 m/s the steady cross wind alone, with nothing random in it, spoiled one landing in four and carried about half of the full package’s rise; gusts and turbulence added about a quarter each and no reinforcement between them was found. At 1.25 m/s the steady wind alone spoiled none.</description><pubDate>Sat, 10 Oct 2026 12:00:00 GMT</pubDate></item><item><title>The pass that was already too close.</title><link>https://wooh.lv/equilibrium/flight-log/the-pass-that-was-already-too-close/</link><guid>https://wooh.lv/equilibrium/flight-log/the-pass-that-was-already-too-close/</guid><description>Nearly every mid-air contact under altitude assignment followed a grant made while the pair was already inside its safety distance. Withholding exactly those grants, with knowledge no craft has, removed most of the excess and kept a smaller loss reduction.</description><pubDate>Sat, 10 Oct 2026 12:00:00 GMT</pubDate></item><item><title>Bad landings grow steeply with cross wind.</title><link>https://wooh.lv/equilibrium/flight-log/bad-landings-grow-steeply-with-cross-wind/</link><guid>https://wooh.lv/equilibrium/flight-log/bad-landings-grow-steeply-with-cross-wind/</guid><description>Between the tested 1 m/s and the 2 m/s that stopped the pad, bad endings rose from about 10 to 26 to 46 per 100 scheduled landings.

Speed-matching with the other level carried the lost craft across the lane; switching it off removed the wall losses in the tested crossing, at the price of more band exits.</description><pubDate>Mon, 05 Oct 2026 12:00:00 GMT</pubDate></item><item><title>When an assigned altitude hides a conflict.</title><link>https://wooh.lv/equilibrium/flight-log/when-altitude-assignment-hides-a-conflict/</link><guid>https://wooh.lv/equilibrium/flight-log/when-altitude-assignment-hides-a-conflict/</guid><description>Fewer lost craft can conceal a shift from wall strikes to mid-air contacts.</description><pubDate>Mon, 05 Oct 2026 12:00:00 GMT</pubDate></item><item><title>Slower is not always a better landing.</title><link>https://wooh.lv/equilibrium/flight-log/slower-is-not-always-a-better-landing/</link><guid>https://wooh.lv/equilibrium/flight-log/slower-is-not-always-a-better-landing/</guid><description>A landing controller helped in the tested disturbance.
